SUMMARY
The development of modern dentistry is primarily associated with the implementation of new technologies and the use of innovative materials for the restoration of dental hard tissues. These materials enable the optimal functional and aesthetic restoration of teeth with a deficiency of hard tissue. The restoration of devital teeth after endodontic treatment is a particularly important issue in dental practice. In this process, the coronal part of the tooth is restored either directly or indirectly. In the direct restoration method, the anatomical form and function of the tooth are restored using composite materials, which ensures a minimally invasive approach and maximum preservation of the tissues. In indirect restoration methods, laboratory-fabricated prosthetic elements such as inlays, onlays, overlays, or crowns are used, providing long-term durability and high aesthetic results. Modern scientific research shows that the use of fiber-reinforced posts in the restoration of devital teeth increases the mechanical strength of the root and prolongs the lifespan of the crown. Additionally, crowns and inlays made from zirconia and other ceramic materials meet aesthetic requirements and cause minimal trauma to the periodontal tissues. Clinical practice confirms the advantages of conservative approaches, as they maximize tooth tissue preservation and reduce the risk of postoperative complications.
